Electronic cigarette

Abstract

An electronic cigarette, comprising a casing and an electrode assembly disposed therein; the electrode assembly comprising an outer electrode ( 30 ) and an inner electrode ( 40 ), which are insulated from each other; outer electrode ( 30 ) being provided with a first through-hole ( 312 ); inner electrode ( 40 ) being provided with a second through-hole ( 412 ); first through-hole ( 312 ) and second through-hole ( 412 ) communicating to form the gas flow communication channel of the electronic cigarette. The electronic cigarette causes gas to flow directly from the first through-hole ( 312 ) to the second through-hole ( 412 ), thus shortening the flow path of the gas, making gas flow changes more smoothly, and reducing noise when smoking, improving user experience.
